Introduction

The Java TimeZone class represents a time zone offset, and also figures out daylight savings.Following are the important points about TimeZone −

• It takes into consideration various time zone.

• Through the method used under this class a program running in any country, gets a TimeZone object based on that particular country's time zone.

Getting Default Timezone for the Current Host Example

The following example shows the usage of Java TimeZone getDefault() method to get the default TimeZone object for this host. We've created a TimeZone using getDefault() method and then printed it.

package com.tutorialspoint;

import java.util.TimeZone;

public class TimeZoneDemo {
   public static void main( String args[] ) {

      // create default time zone object
      TimeZone timezonedefault = TimeZone.getDefault();      

      // checking default time zone value          
      System.out.println("Default time zone is :\n" + timezonedefault);
   }    
}

Output

Let us compile and run the above program, this will produce the following result.

Default time zone is :
sun.util.calendar.ZoneInfo[id="Asia/Calcutta",offset=19800000,dstSavings=0,useDaylight=false,transitions=7,lastRule=null]
